Pregunta 8
Pregunta
Trichromatic colour theory: What did Young, Helmholz state about colour? (before it was backed up by physiology)?
Respuesta
We only need a few photoreceptors and can figure out any colour from their relative responses
We only need a few photorecpetors, which combined can make any colour
We need many photoreceptors and work out colours based on their relative responses
We need many photoreceptors each with it's own colour
Pregunta 9
Pregunta
Trichromatic Colour Theory: Outline Hering's Opponent-Process Theory
Respuesta
Primary colours are in opposing pairs, see colours in terms of how much of one extreme it is
All colours are in opposing pairs, see colours in terms of how much of one extreme it is
Primary colours are in opposing pairs, see colours in terms of how one pair relates to other pairs
All colours are in opposing pairs, see colours in terms of how one pair relates to other pairs
Pregunta 10
Pregunta
Why when looking at a pattern, do we see the image in the opposite colours when presented with a white screen?
Respuesta
We adapt to the colour presented, so the opposite colour is more strongly activated in relation
We adapt to the opposite colour, so the presented colour is more strongly activated in relation
The pupil absorbs the light of the original colours and reflect them back onto the white surface, and opposing colours are perceived to refraction
Our brain fill sin the gaps of what it thinks we should see, and because the presented colours have adapted, the opposing colours are the closest matched
